HEKTOGRAPH-GAGE.

SPECIFICATION forming part of Letters Patent No. 333.115, dated December29, 1885.

Application led January 24, 1885.

.To all whom t may concern:

Be it known that I, FRANK M. DUNBAR, a citizen of the United States,residing at Titusville, in the county of Crawford and State ofPennsylvania, have invented a new and useful Hektograph-Gage, of whichthe following is a specication.

My invention relates to the use of the hektograph or gelatine pad fortransferring copies of writing from the original to other sheets, myobject being to construct a gage' so that all copies made shall be inthe proper relative position on the different sheets, as would be nec-Aessary in the filling up of printed blanks or of "copying indorsenientson insurance-policies.

I attain this by the device illustrated in the accompanying drawings, inwhichM Figure l is a front view; Fig. 2, a section on line x y in Fig.l, and Fig. 3a section View on line a bin Fig. l. Y

. Similar letters refer to similar parts.

A A is a plain iiat sheet, of metal, paper, or other suitable material,(sheet iron, tin, or brass being preferab1e,) with the rectangularopening B B at any point and of any size as may be required.

C is a gage-slide with the ends G G folding' over and embracing thesides of the plateA A, but fitted to slide up and down along the faceofthe plate. The upper edge of the slide C is formed into the raisedledge or rim D.

The operation is as follows: The gelatine pad having been prepared, andthe transfer to it of the original writing having been made, the plate AA is so placed upon the pad that the writing shall be central with theopening B B. The slide C is then adjusted so that the rim D shall be theright distance above the opening B, so that the transfer back to thesheet shall come in the right position. The sheet is then placed withAthe top end against the rim D and the impression taken. It is Serial No.153,826. (No model.)

sheet being determined by measure on the scale F, the slide C is adjusted so that the rim D shall be the proper distance above the openingB.

The device may be used Without the slide C and rim D, using merely theplateA with the opening B, a mark on the plate A taking the place of therim D. Convenience, however, requires -the slide and rim. rlhe plate,with the opening, is also useful in taking copies in the ordinarymanner, and Where it is not required to gage the position.

By placingthe plate A over the pad, with the opening over the impressionof the writing, copies may be taken Without having the entire sheetadhere to the surface of the gelatine, as where there is no interveningsubstance.

I claim as my invention- 1. Ahektograph-gage consisting of the plate AA, with the opening B B, and slide C, with the raised rim D, alloperating substantially as shown and described.

2. Ahektographgage consisting of the plate A A, with the opening B B,and slide C, with the raised rim D, and with the scales E E and F, alloperating substantially as shown and described.
